SoapElementAttribute.IsNullable Property

 

Gets or sets a value that indicates whether the XmlSerializer must serialize a member that has the xsi:null attribute set to "1".

Namespace:   System.Xml.Serialization
Assembly:  System.Xml (in System.Xml.dll)

public bool IsNullable { get; set; }

Property Value

Type: System.Boolean

true if the XmlSerializer generates the xsi:null attribute; otherwise, false.

The XML schema specification for structures allows an XML document to explicitly signal that an element's content is missing. Such an element contains the attribute xsi:null set to "1". For more information, see the World Wide Web Consortium (www.w3.org) specification named "XML Schema Part 1: Structures".

If the IsNullable property is set to true, the xsi:null attribute is generated for class members that have been set to null. For example, if you set a field named MyStringArray to null, the XmlSerializer generates the following XML code.

<MyStringArray xsi:null = "1" />

If the IsNullable property is false, no XML element is generated.

System_CAPS_noteNote

You cannot apply the IsNullable property to a member typed as a value type because a value type cannot contain null.
